How to use

In your markdown files:

[codeSelector]
```php
<?php
use ApiPlatform\Core\Annotation\ApiResource;

/**
 * @ApiResource(itemOperations={"get"})
 */
class Book
{
    //...
}
```

```yaml
App\Entity\Book:
    itemOperations:
        get: ~
```

```xml
<?xml version="1.0" encoding="UTF-8" ?>
<resources xmlns="https://api-platform.com/schema/metadata"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="https://api-platform.com/schema/metadata
           https://api-platform.com/schema/metadata/metadata-2.0.xsd">
    <resource class="App\Entity\Book">
        <itemOperations>
            <itemOperation name="get" />
        </itemOperations>
    </resource>
</resources>
```
[/codeSelector]

The code selector is not stylized by default. You can add your own CSS by using the following class names:

• code-selector for the whole selector
• code-selector-toolbar for the container of the select buttons
• code-selector-select-php for a particular button
• code-selector-code-php for a particular code block
